A: Mold has the potential to cause health problems and even make a home uninhabitable. However, everyone is affected differently when in contact with mold. The mold that may not bother a seller may affect the buyer.

Some mold can produce allergens, irritants, and in some cases, potentially toxic chemical substances known as mycotoxins. People who are sensitive and exposed to mycotoxins can become ill. Allergic reaction to mold is common. They can be immediate or delayed. People diagnosed with allergies and asthma may be very sensitive to mold. Mold can cause asthma attacks. Others at risk may include: infants, children, women, and individuals with existing respiratory conditions.
